The iTunes app review processes has been very slow lately, and now that it is moving again there seems to be a weird streak of similar apps. 3 Remote Mixers and now 2 motion based music apps! MoovFX Echo hit the App Store in the same hour as MIDI In Motion. Obviously the reviewers are trying to pit them against each other. 2 Apps enter, 1 app leaves!

MoovFX Echo is a motion based Echo effect for guitars, as you may have guessed by the name. Just plug your guitar in, strap your iPhone to the guitar and commence the jiggling. There are 4 different echo types available, with controls to match BPM and limit the range of motion.

There are paid and free versions, but they make no mention of exactly what is different other than the "Lite" being feature crippled.
